Why do some V8 cars have more horsepower than other V8 cars?

Question

For example, a V8 Bi-Turbo G63 AMG has 577 BHP and a Twin-Turbo V8 Koeniggsegg has 1160 BHP. How do virtually the same engines have such a large discrepancy?

Answer 1

Your definition of “virtually the same” is incorrect. The G63 is luxury SUV and the Koeniggsegg is a barely legal race car.

Yes, both have dual turbo 5L-ish V8 engines, but all the fuel management and engine computer controls are completely different.
